915201 - Trim unnecessary parts of the build out of B2G JB emulator builds

Status: RESOLVED FIXED

(Firefox OS Graveyard :: GonkIntegration, defect)

Description

[Ryan VanderMeulen [:RyanVM]]

B2G JB builds take 3+ hours vs. 2ish hours for their ICS counterparts. This makes sheriffing a big pain due to the long cycle time, and it will get worse when we actually start running tests on these builds additionally.

mwu says he can kill a couple things (like clang) from the build, which should help get the compile time down.

I can remove clang/llvm as soon as bug 915285 is fixed.

These changes reduced the build time by roughly 60 minutes on the JB emulator and Nexus 4.

I don't have any more ideas for speeding up the build at the moment. Resolving - we can open new bugs when there's more ideas.
